AbstractIn this dissertation a characteristic equation has been obtained, in the framework of the linear theory of elasticity, for multilayered pipes; individual layers are made of isotropic elastic solids. A theoretical study of the Lamb wave propagation in multilayered pipes for both axisymmetric and nonaxisymmetric loading is presented. The stress and displacement variations inside the multilayered pipe are theoretically calculated for a number of propagating Lamb modes. The Lamb wave dispersion curves and the curves of frequency versus the ratio of wall thickness to half wave length have been computed for different Lamb modes inside a homogeneous pipe and have been compared with published results. These computations are extended to multilayered pipes.
